@ther objects of the imfention` Wiii be noted in eonneetion with the'descliptien of the iiiustrnted embodiment thereof.

The invention consiste in the improved Wax pot iieieineitei described and deiined in the claims.

in the drawings Figure i is e side eievatien et e wm; pet embodying the present in yentien, with. parts broken away to show the interior Construction; Fig. is en elevation, pei'tiy in section, rlooking iiem iight to ie'ft in Fig. l; Fig. 3 a perspective vicwet Vthe threeCl-guiding devices.

The iiiusti'atefi embodiment. ot the iiivention is constructed feiiewsi-'ihe supply 0i. meitefi wir; is contained e Teeeptzicie l pievided with n. cm'ei i? seeniefi thereto by thumb screws 3. /fiiiiy-tinfeed teneien i of ordinary inem maintains the thread undef slight tension, and from this tension device the thread passes thi'eugh e tube 5 iixefi at its Upper end in the @over 2, te i 4pulley 6 which is jeurnuiefi en a henge 7 fixed te the lower enti et' the tube 5. .fitter passing about the piiiiey the thread passes upward through tube 8 to fi Stripper 9, of eiriinzuy form, and thence to the sewing meeiiine. The puiiey 6, being located nem* the bottom oi' the. wax receptacle i, causes the thread te pass through the body of meited Wax se ns te become waxed, and the stripper 9 iemmes the surplus Way. in the usuni manner. The ti'ii'eefigi'aiiing devices Me set 'et :1. siigiit. angiea es shown in Fig. i., in eidei.' that the thread delivered from them muy lead fiiectiy te the seiving ii'inehine.

The reeeptacie i is normally heated, Cim?- ine; the operation of the sewing( machine,l by a heating' cheinher 10 foi-*ned integifei with the bottoni of t'ic Wax reeeptncie. The heeting chamber contains cii which is heeteci by e steam eeii 1i. The eoii'il is ted by pipe 1Q, 'which is pieie'iihiy connected with the heating sieviees et the Sewing mw chine ee as to receive exhaust steam them from. The Steam. after passing thz'ough the steam ceii'l-L exhausted through e. pipe 13. By using exhaust Steam in this msmnei' the heating; of the wen pet is ecenomicaiiy peeeimecia and the heating chamber is prepertioneii te the Wax itacle that it eennet eveeheet the Wen ci' cause it te beii.

The auxiliary heating device for expediting the melting of the cold wax when the wax pot is first put into operation comprises a heating` chamber 14- which is fixed at its upper end to the wall of the wax receptacle land bends downwardly so as to depend into and be entirely surrounded by the wax inthe wax receptacle. The auxiliary heating chamber is illcd with oil, which is heated by a steam coil 15 fed with live steam through a pipe 16 controlled by a valve 17. The exhaust steam from the coil'l passes through a pipe 18 to the exhaust pipe 13. As shown in Fig. 1, the pipe 18 is curved to permit it to expand and contract freelyv without straining the joints.

In order that the fresh unmelted wax which is supplied to the wax pot from time to time during the continued operation of the wax pot may not come in contact with the thread, al' separate receptacle 19 is provided with a loose cover Q0, the two recept-acles being` connected by an opening 21 at the bottom ot' the receptacles 19. rEhe coldf" thereafter kept heated' to the proper temperature by theheating chamber 10, Without attention on the part of the operator.

The present invention is not limited to the details of construction and operation of the illustrated embodiment, but may be embodied in other forms broadly defined in the claims.

Having now described thcinvention, what is claimed is :ei

1. A wax pot for sewing machines, having, in combination with a sewing machine and steam heating` devices therefor, a receptacle for melted wax, a heating chamber therefor fed with exhaust steam from the heating devices of the sewing machine, an

auxiliary heating chamber fed with livev steam, and a valve for shutting the steam off from the auxiliary chamber when the wax has become melted, substantially as described.

2. A wax pot for sewing machines, having in combination a receptacle for melted wax, a heating' device extending into the wax pot'so as to 4be surrounded by the wax, and a heating device located outside of the wax pot, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses. WILLIAM C. MEYER.
